More and more Canadians are replacing regular incandescent light bulbs with more energy-efficient products, such as compact fluorescent lamps (CFLs).
But while CFLs are being promoted because they are energy-efficient, their use has also raised health concerns.

There’s some progress, but we’re still not quite there. Home Depot is selling a Philips LED light bulb: same brightness as a 60W incandescent bulb (in other words, dim), same shape as standard A19 bulb, same color temperature and color rendering index, and dimmable, uses 12W, and lasts for 25,000 hours — Cost: $40.

Light your home using the same amount of light for less money. Upgrading 15 of the inefficient incandescent light bulbs in your home could save you about $50 per year. New lighting standards take effect in 2012, and money-saving options such as halogen incandescent, CFL, and LED light bulbs are available today.

There is the white light and there are the red, green, blue ones (or RGB). In the example we're using, of television, white lights are typically used for edge-lit TV screens (white light diodes are placed around the screen's perimeter). With RGB LEDs, though, they are typically behind the LCD panel, providing a uniform color range behind the screen.

SMD LED stands for surface mount LED. Specifically, it's a light-emitting diode that is mounted onto and soldered onto a circuit board. An SMD LED is quite small since it has no leads or surrounding packaging that comes with a standard LED...
